What does it addEdit
OptiFine is mostly used to prevent common lags, and lagg spikes. It also enable the use of HD texturepacks without using MCPatcher.
We have this mod installed because of the HD texturepack feature, and because all these mods may lag some (old) computers.
If you don't need it, then pretend like it is not there. If you need it to prevent lags, go into the options menu, then go to video options, and tweak the settings till you think it is right.
